Accompanying drawing explanation
Fig. 1 is the structural representation of the spray device of band of the present invention.
The specific embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
The spray device of band of the present invention is mainly for the production of nanocrystalline strip.
Fig. 1 is the structural representation of the spray device of band of the present invention, as shown in the figure, this device comprises crucible 11, involucrum 12, clad 13, heating globar 14, water cooling plant 15, temperature sensor 21, float lever 22, air inlet pipe 23, escape pipe 24, funnel 31, stopper 32, nozzle 33.
Crucible 11 is for the molten steel of accommodating melting, and the bottom of crucible has consent 16, and consent 16 adopts separate type, at crucible 11 bottom thickness limited in the situation that, guaranteed the effective length of consent 16, consent 16 is position easy to wear, adopts separate type more easily to change.Involucrum 12 is wrapped in the outside of crucible 11, and involucrum 12 adopts metal material to make.Clad 13 is connected on involucrum 12 by bolt card, thereby forms confined space with involucrum 12.Heating globar 14 is plugged on involucrum 12, for heating involucrum 12 and crucible 11, thereby by heat exchange, keeps the temperature of crucible 11 interior molten steel.Water cooling plant 15 is wrapped in the outside of involucrum 12, is welded on clad 13, for reducing the temperature of involucrum 12, prevent involucrum 12 temperature distortions of metal material, meanwhile, can also be used to seal clad 13 and the confined space that involucrum 12 forms, prevented the phenomenon of gas leakage decompression.
Temperature sensor 21, is plugged on clad 12 hermetically, and is inserted in crucible 11, for measuring the temperature of crucible 11 interior molten steel.Float lever 22 is plugged on clad 12 hermetically, is inserted in crucible 11 and floats on molten steel, for measuring the liquid level of crucible 11 interior molten steel.Air inlet pipe 23 is plugged on clad 12 hermetically; for carrying gas to involucrum 12 and the confined space that clad 13 forms, thereby exert pressure, for example, can select nitrogen or argon gas; not only play the effect of pressurization, can also prevent as protective gas the oxidation of crucible 11 interior molten steel.Escape pipe 24 is plugged on clad 12 hermetically, for the confined space output gas forming from involucrum 12 and clad 13, for confined space decompression, generally, escape pipe 24 is in sealing state, when suspending operative installations or producing end, the decompression of exitting of the escape pipe 24 that can open sealing, when pressurization is excessive, also can reduce pressure by escape pipe 24, be used in conjunction with and can the pressure in seal cavity be regulated with air inlet pipe 23.
Funnel 31, is plugged on clad 12 hermetically, and inserts in crucible 11, for molten steel, flow into crucible 11, air tight in order to guarantee confined space, in the interior molten steel of crucible 11 position, reach while setting level value, the bell mouth of funnel 31 is sealed up, prevent from leaking gas in device busy process.Stopper 32, be plugged on hermetically on clad 12, and be plugged in crucible 11, for controlling the flow that flows out molten steel from consent 16, the head of the stopper 32 of pegging graft with consent 16 adopts inclination angle to arrange, consent 16 also adopts the inclination angle being mated to arrange, when stopper 32 moves upward, stopper 32 increases gradually with the gap of consent 16, it is large that the molten steel flow flowing out also becomes gradually, until extracting consent 16 flows completely, stopper 32 will remain unchanged, when stopper 32 moves downward, stopper 32 reduces gradually with the gap of consent 16, the molten steel flow flowing out also reduces gradually, until stopper 32 completely seals and contacts with consent 16, now, molten steel in crucible 11 no longer flows out.Nozzle 33, dock with consent 16, molten steel liquid level in crucible 11 reaches setting level value, pressure in confined space reaches setup pressure value, and when the liquid steel temperature in crucible 11 reaches set temperature value, control the space between stopper 32 and consent 16, the molten steel in crucible 11 will flow out by consent 16 and nozzle 33 successively.
Further, in crucible 11, be provided with slag trap 17, for filtering the molten steel that flows into interior consent 16 1 sides of crucible 11.In whole device, need the position of sealing all to adopt rubber seal to seal it, to guarantee the sealing of confined space.
The spray device specific works of band is as follows:
The molten steel of melting enters in crucible by funnel 31, and molten steel enters a side of the crucible 11 that is provided with consent 16 by slag trap 17, when float lever 22 measures molten steel liquid level, reaches while setting level value, stop passing into molten steel in crucible 11, and by funnel 31 sealings; Now by air inlet pipe 23, in confined space, input gas, when the gas pressure in confined space reaches setup pressure value, stop exerting pressure, in the course of the work, along with the continuous variation of crucible 11 interior molten steel liquid levels, need to control device for exerting, guarantee that the pressure in confined space is constant voltage; Meanwhile, adopt 21 pairs of interior liquid steel temperatures of crucible 11 of temperature sensor to detect, temperature detected and whether reach set temperature value; When molten steel liquid level reaches when setting level value, gas pressure and reaching setup pressure value and liquid steel temperature and reach set temperature value, control the gap between stopper 32 and consent 16, molten steel in crucible 11, under pressure constant state, will flow out to carry out follow-up spray band process by consent 16 and nozzle 33 successively.For example, when the interior temperature of crucible 11 reaches 1400 ℃ of set temperature value, the interior molten steel capacity of crucible 11 reaches setting value 400kg, while being 0.3MPa by air inlet pipe 23 to applied pressure in confined space, use the spray device of band of the present invention to carry out pressure spray iron based nano crystal band, the iron based nano crystal band tape thickness of preparation is 22 μ m.
The spray device of band of the present invention; employing passes into the protective gas of nitrogen or argon gas in the confined space of involucrum and clad formation; make confined space produce constant pressure; thereby obtain the highdensity ultrathin nanometer of pressure spray crystal zone material, passing into of protective gas also protected the molten steel in crucible not oxidized simultaneously.The setting of water cooling plant outside involucrum, has not only played the effect of cool metal involucrum, but also has played the effect of sealing confined space, has realized pressure spray band, has reached the effect of producing at a lower temperature highdensity ultrathin nanometer crystal zone material.
The above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only the specific embodiment of the present invention; the protection domain being not intended to limit the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
